OVERHEAD CONVEYER SYSTEM.

Application filed February 11, 1921. Serial No. 444,113.

To 1/7] lc/ium if may concern l e itknown that l. (Lyme Xmas. a citi- '/.en of the l nited States. residing in the city of lllkhart. county of lllkhart. Indiana.

have invented certain new and useful linprovements in an ()verhead (onveyer h'ystem. of which the following is a specification.

This invention relates to overhead conveyers in which a bucket is moved from one place to another. and more especially to a dumping bucket and mechanism for the filling of the bucket. overhead transportation thereof and the dumping thereof.

The principal object. of my invention is to provide asimple. cheap and durable overhead conveyer device to enable the transportation of coal. and the like. from one place to another not remote location. in which device or system an improved bucket. lilling and dumping mechanism is incorporated. ()ther objects of Iny invention are mentioned and described herein.

lhe preferrtal embmliment of my invention is illustrated in the accompanying drawings in which Figure 1 represents a side elevation of the bucket and tripping mechanism in which the latter is shown disengaged from the bucket bail; Fig. 2 shows the same men'ibers representing the bucket supported by the carriage or trolley for transportation of the loaded bucket: Fig. It represents the same members showing the bucket dumping doors open at the bucket dumping terminal: Fig.1 is an end view of the members shown in l ig. 3: Fig. 5 is a view similar to Fig. .1 but showing a modilied form of the tripping mechanism: Fig. (i is a-bott om plan View of the track. trolley and tripping mechanism shown in Fig. 5; and Fig. 7 is a section taken on the line TT of Fig.

Similar numerals of reference indicate like parts throughout the several views on the drawing.

Referring to the drawings in detail. the numeral 1 indicates a fragment of an overhead track which may consist of a single I beam suitably supported on any kind of l'rameworknot shown. A carriage or trolley having wheels 3. 3. is mounted for movement upon the track 1. to which trolley the traction cables 4 and 5 may be attached for effecting movement thereof either way on said track.

tremitics a pair ct t1. (3 are provided and oppositely intermediate the trolley exof depending hanger brackdisposed the U shaped bail 2*. the upper on the trolley frame. which brackets are suitably apertured to carry the hanger supporting pin T disposed transversely of the trolley. pair of spaced.depending hangers UR maybe mounted for oscillation upon the pin T. each of said hangers being provided with a carrier book 9. trip lever or arm It) is rigidly mounted upon one end of the pin T which is extended for that purpose. said lever or arm extending at substantially right angles to the hanger h and longitudinally of the track 1. A cam or tripping element 11 is rigidly secured to the track 1 bv the braces 12. 12 adapted to be engaged by the end of the trip arm it) for upwardly swinging the latter for actuating the hanger as hereinafter described.

The numerals 13 and 11 indicate a pair of sheaves or rope wheels revolubly mounted in the frames 15 and 16. respectively. at 17 and 1H. res a-ctively. said frames being pivotally mounted on the trolley at 1!) and 2t) respectively. Numeral 21 indicates a bucket body which may be provided with a fixed bail composed of the transverse top bar 22 rigidly connected with the bucket by a plurality of side bars 23. 23 which connect the top bar ends with the corresponding side of the bucket. Numerals 24 and 25 indicate a pair of bucket bottom dumping doors hinged to the bucket at 26 and 27. respectively. and adapted to cooperate. as hereinafter described. to close the bucket bottom. An upright U shaped door actuating bail 2H is carried by the bucket and has its two legs 2H. 2H disposed on opposite sides and exteriorly of the bucket. said bail legs being slidably arranged in a plurality of strap guides 2!). 2%) suitably fastened to the bucket side to enable vertical movement of said bail therein. Intermediate each set of the bail guides 29 a link carrier 30 is rigidly fastened to each leg of the bail 2R. pair of door actuating links 31 and 32 are pivotally connected with the carrier 30 at 33 and 34. respectively. the lower end of-each of said links being pivotally connected with the doors 24 and respectively. at 35 and 36. respectively. A. sheave or rope wheel t? is rotatably mounted in the frame 38 at 39. the lower end of said wheel frame being secured rigidly to the transverse member of end of said sheave frame being extended upward beyond the outer periphery of said sheave. which frame extension is adapted to engage the bail bar 22 to space the sheave there from.

A cable 40 engages the under side of sheave 37 and runs over each of the sheaves 13 and 14, as shown, one end of which cable may be connected with any suitable hoisting device, the other end whereof may be secured to any stationary object.

Normally, the weight of the trip arm 10 will swing the hanger 8 toward the bail 22 when the former is disengaged from the cam element 11. whereby the hook 9 may be projected beneath the bail bar 22. normally. the bucket doors 24 and 25 are held closed by the cable 40 when the latter is rendered taut by the operator. In practice. the bucket bail bar 22 is disengaged from the coupler or hanger hook 9 and the bucket is lowered to the fillingstation or terminal for filling. See Fig. 1. Thereafter,

the bucket is filled and elevated by wind ing up cable 40 and suspended on the coupler book 9, which engages beneath the bail bar 22, for transportation on the trolley 2 to the dumping position. See Figures 3 and 4. At this point the cable 40 is slackened which permits the weight of the bucket contents to force open the bucket doors 24. and 2."), thereby dumping the bucket in midair. Thereafter, the bucket is returned to the filling station where the coupler 8 is disengaged from the bail bar 22 to enable the refilling of the bucket when lowered.

In Fig. 2 the bucket is shown in transit with the cable 40 taut to maintain closure of the bucket doors. In Fig. 5 a modification of the cam device is shown to enable the operation of the trolley 2 either way from a bucket filling station which may be positioned intermediate the extremities of an overhead track. In thisstructure a double cam element is used which may comprise the diverging cam bars 41 and 42 downwardly inclined from the extremities of the horizontal connecting bar 43, which element may be secured to the overhead track 1 by the brackets 44, 45 and 46. For adaptation to this structure the trip arm 10 may have alaterally projecting pin 47 to engage'and ride upon the cam elements 41. 42 and 43.

The bucket 21 may be provided with a pair of oppositely disposed wheels or roll.- ers 48 and 49 suitably journaled on bearing pins 50 Which are rigidly mounted in and project laterally from the bail bars 28',

which rollers are adapted to engageim olined tracksnot shown for lowering the bucket into a pit-not shoWnand for elevating it therefrom.

I claim:

1. In combination, a track; a trolley movable on said track; a coupling element on And.
